It seems like a major point of Anglicanism is the belief in localities possessing independent authority, one from another. So, for example, the Archbishop of Cantebury (sp?) is not the English Pope, the supreme head of the Anglican Church. Instead, he is considered "first among equals," along with other clergy.
So, if I've come to believe that God ordained authority (apostolic succession?) is primary, I don't think I want to buy into a church that seems to not practice this. The point of putting your faith in authority is to believe the ladder runs all the way to the top.
So, it begs the question, why not become Catholic?
